Pytest Coverage Measurement

Purpose

Code coverage measures how much of your code is tested. This skill provides strategies for meaningful coverage measurement and improving test quality.

When to Use This Skill

Use when measuring test coverage with "measure coverage", "track coverage", "identify untested code", or "set coverage thresholds".

Do NOT use for writing tests (use layer-specific testing skills), pytest configuration (use pytest-configuration), or fixing low coverage (identify gaps first, then use appropriate testing skill).

Quick Start

Generate coverage report:

# Generate HTML coverage report
pytest --cov=app --cov-report=html --cov-report=term-missing
